A) \[4\times {{10}^{-15}}\]
B) \[4\times {{10}^{-10}}\]
C) \[1\times {{10}^{-15}}\]
D) \[1\times {{10}^{-10}}\]
Correct Answer: A
Solution :
\[A{{B}_{2}}\,\underset{S}{\mathop{{{A}^{2+}}}}\,\,\,+2\,\underset{2S}{\mathop{{{B}^{-}}}}\,\] \[{{K}_{sp}}=[{{A}^{2+}}]\,{{[{{B}^{-}}]}^{2}}\] \[=(S)\,{{(2S)}^{2}}=4{{S}^{3}}\] \[=4{{(1\times {{10}^{-5}})}^{3}}\] \[=4\times {{10}^{-15}}\]You need to login to perform this action.
